Title: Manufacture of semiconductor device
Inventor: ITO HIROSHI
IPC: H01L21/3205
Filed: 1990-08-17
Abstract: PURPOSE:To obtain a stable via-hole resistance, to restrain the hillock of an Al interconnection and to enhance the reliability of a semiconductor device by executing the following: a process which forms a second interlayer insulating film by a coating and baking method and which executes a heat treatment in order to discharge a gas in the second interlayer insulating film; and a process to deposit a third interlayer insulating film on the second interlayer insulating film immediately after the heat treatment. CONSTITUTION:First, a lower-layer Al interconnection 2 is patterned and formed on an insulating film 1 formed on a semiconductor substrate. Then, a plasma oxide film 3 is deposited by a method to treat a process from the heating start of the substrate till the growth start of the plasma oxide film in a short time. Then, a solution composed mainly of a silicon compound is coated and baked; a silica insulating film 4 is formed; the surface is made smooth. Then, a silicon oxide film 5 is deposited by a normal-pressure chemical vapor growth method. The substrate is heated sufficiently by utilizing a heating operation; the moisture in the silica insulating film 4 is driven off. Then, a silicon oxide film 5 is deposited. Even when a heating operation is executed at this time, a hillock is not grown on the Al interconnection 2. When an Al layer for upper-layer interconnection use is formed by a sputtering method, it is possible to restrain a gas from being generated from the silica insulating film 4 at the side face part of a via hole.

Abstract: PURPOSE:To produce a highly syndiotactic styrenic polymer at a high productivity by continuously supplying to a horizontal self-cleaning reactor a styrene monomer and a catalyst both divided into several portions along the axial direction of the reactor and polymerizing the monomer. CONSTITUTION:A horizontal self-cleaning twin-screw reactor is partitioned into several parts along the axial direction, and these parts (F1, F2, F3, etc.) are each equipped with a jacket (J1, J2, J3, etc.) through which cooling water passes, monomer nozzles (M1, M2, M3, etc.) which supply a styrenic monomer, catalyst nozzles (C1, C2, C3, etc.) which supply a catalyst, and temp. measurement means (T1, T2, T3, etc.). Thus, the catalyst alone or together with the monomer is divided along the axial direction of the reactor and continuously supplied to the reactor where the monomer is polymerized, thus continuously producing a highly syndiotactic styrenic polymer. Examples of the catalyst are methylaluminoxane and triisobutylaluminum.

Abstract: PURPOSE:To prevent precipitation of crystals, etc., during long term storage and to obtain a stable image by using a specified compd. as a silver halide solvent. CONSTITUTION:An imagewise exposed photosensitive silver halide emulsion layer is developed in the presence of a developing agent, the silver halide solvent, and alkali, at least a part of the unexposed silver halide of the emulsion layer is converted into a silver complex salt, and at least a part of the complex salt is transferred to an image receiving layer having a layer contg. silver precipitating nuclei to form an image in the diffusion transfer process. The silver halide solvent to be used at that time is represented by formula I in which R<1> is -OR<3> or formula II; R<3> is H, alkyl, cycloalkyl, aryl, or the like; R<4> is a C group necessary for forming a hetero ring contg. O; R<2> is H or a substituent; X is alkylene; and (n) is 0-5. Such a compd. may be incorporated in the photosensitive element, or the image receiving element, bit it is, preferably, contained in a processing element. The use of this compd. permits precipitation of crystals and salting out products to be prevented during long-term storage, and a stable image to be obtained.

Title: Image compressing method
Inventor: GUREGORII ESU YOBANOFU
IPC: H04N7/30
Filed: 1996-08-19
Abstract: PROBLEM TO BE SOLVED: To provide a twice path system compression method completely in compliance with the JPEG in which an optional image is compressed in a predetermined fixed capacity of a buffer. SOLUTION: A compression coder and method estimate (356) an activity reference value based on a mean sub of absolute values of quantized DCT coefficients for each block. With the activity reference value estimated, a mathematic model associated with an image activity to a Q factor relating to a prescribed JPEG object compression ratio provides an estimate Q factor generating a design object ratio (358). The mathematic model is generated in a calibration stage executed in off-line only once as to a provided image acquisition device. Since the activity reference is calculated, based on the quantized DCT coefficients, the efficient implementation of the coding in compliance with the JPEG is attained from the standpoint of the processing speed and from the standpoint of the memory capacity.

Title: Non-contacting measuring method of radius of curvature
Inventor: OIDE TAKAHIRO
IPC: G01B11/24
Filed: 1990-08-20
Abstract: PURPOSE:To realize non-contact measurement by a method wherein, while the distance between a body to be detected and an objective lens system is changed, the radius of curvature of the body is obtained on the basis of the difference of the distances when two peaks appear in the outputs detected by a photodetecting means. CONSTITUTION:When a three-dimensional table is gradually drawn closer to an objective lens 20 from below, a first peak appears. That is, when a focus of the light beam converged by the lens 20 is met on the surface of a ball 11, almost all the light reflected by the ball 1 is condensed by the lens 20 and converged on a solid-state image sensor of a photodetector device 30, whereby a spot is formed. When the three-dimensional table is raised further, if the light beam projected from the lens 20 is incident upon the ball 11 in such a manner as to be condensed to the center of the ball 11, namely, to the center of the curvature, almost all the light reflected by the ball 11 is condensed by the lens 20, forming a spot on the solid-state image sensor. A second peak appears at this time. Therefore, the moving distance of the three-dimensional table when the first and second peaks appear is equal to the radius of the ball 11.

Abstract: PROBLEM TO BE SOLVED: To constitute a cycloconverter of a small-sized thyristor having a low breakdown voltage and, at the same time, to increase the output of the converter, by constituting each variable control bridge in a state where two half-wave converters are superimposed upon another in two stages by making the cycloconverter, in such a manner as to make voltage doubler rectifier operations by connecting the neutral point on the single-phase AC output side to the neutral point of three-phase windings. SOLUTION: Cycloconverters are made to perform voltage doubler rectifier operations by connecting the connecting point C of an LC filter 3 for removing the harmonic components of half-wave currents generated from upper-stage converters BC1U and BC2U, with that of another LC filter 4 for removing the harmonic components of half-wave currents generated from lower-stage converters BC1L and BC2L, namely, by connecting a neutral point formed on the single-phase output side and the neutral point of three-phase main coils 1. Therefore, the converters EC1 and BC2 are constituted by respectively superposing the upper-stage converters BC1U and BC2U upon the lower-stage converters BC1L and BC2L. In this case, it is preferable to use a permanent- magnet generator having a permanent-magnet rotor as a three-phase generator.
